在window上搭建process.env.HOME 找不到值报错

[zwwtj2014]

下面两处代码，process.env.HOME 在window下取不到值，导致在给join方法传参的时候抛异常，可以考虑有os.homedir() 取代吗？

https://github.com/cnpm/cnpmjs.org/blob/master/bin/cli.js#L54
var dataDir = options.dataDir || path.join(process.env.HOME, '.cnpmjs.org');

https://github.com/cnpm/cnpmjs.org/blob/master/bin/cli.js#L97
var dataDir = options.dataDir || path.join(process.env.HOME, '.cnpmjs.org');

可以考虑在环境变量中设置HOME

set HOME=%USERPROFILE%
npm run start

或者这么改

var dataDir = options.dataDir ||  path.join(process.env[(process.platform == 'win32') ? 'USERPROFILE' : 'HOME'], '.cnpmjs.org');

//or

var dataDir = options.dataDir ||  path.join( process.env['HOME'] || process.env[ 'USERPROFILE'] , '.cnpmjs.org');
